The grooves are so formed that the jets diverge slightly so that when the shower head is positioned at the proper height over a bath tub, the area covered by the spray delivered by the shower head will be slightly less than the opening of the tub.

By varying the angle of divergence of the grooves, it is possible to more or less fill with jets the area outlined by the spray.

Bar I3 is cast integrally with the shell proper and its function is to facilitate boring out of the cavity for the flow obstructing member l8.

While bar I2 has a similarfunction to bar I3,

it has an added and important functiom as will H be hereinafter pointed out.

The end of flow obstructing member l8 oppovents complete rotation of the flowobstructing member l8 (because of the shoulder'formed by the cut away portion 30) and limits the move ment of the flow obstructing member to a back and forth oscillation. 7 When the flow obstructing member is in operative position its cylindrical surface Willbe down and handle 21 will be in down position as shown in Fig. 1 so that the jets are defined by the grooves 29 and the curved walls of ledges l4 and I5. With the parts in this position, the two series of jets will discharge a spray of more or less rectangular outline and the two series will'discharge. the streams or jets more or less parallel, one seriesto the other, although one half the jets of each series will slightly diverge from those of the other half. f By turning the handle to one side or the other, a flushing opening 32 is providedalongside of the flow obstructing member. This is clearly shown in Fig. 3. By turning the handle to the other side, a corresponding opening will beprovided on theopposite side of the flow obstructingmember. By thus manipulating the handle, chipsor loose sediment or other dirt which has collected in theshower head may be readily discharged. By loosening follower nut 20 without removing the handle 21 the flow obstructing member may be removed from its bore and any sediment or deposit which has collected in grooves 29 -may be cleaned therefrom by means of a brush. Since a preformed packing is utilized, the different parts of the flow obstructing device may be removed as a unit and may also be replaced asa unit. This provides a ready way of removing deposits such as lime deposits which always collect in shower head spray openings. 7

If the flow obstructing memberis oscillated with the water pressureon, the series. of jets on one side or the other as the case may be, willhave .the shower head is located. By means of these extended walls 33 and 34 andbar or bridge member l2, the walking Jets are intercepted the jets are broken up and the water will fall in the form of drops into the receptacle.

The arrangement is such that the flow obstructing member is in operative position when the handle is turned straight down. There is intended to be no adjustment of the spray head, but it is supposed to be either in operative position or in one or the other of its flushing positions.

In the form shown in Fig. 6, the grooves instead of being formed in the flow obstructing t law.

The grooves in the ledges Ma and |5a may be positioned at different angles so as to properly direct the individual jets forming the spray.

A follower nut with a preformed packing and follower and the same type of a handle may be used as shownin the other form in Figs. 1'-5 inclusive and when it is desired to clean the grooves in ledges Ma and Ilia the flow obstructing' member may be removed and the grooves may be cleaned bymeans of a brush, as wnr be readily apparent. A thin, fiat brush may be inserted within the space usually occupied by the flow obstructing member and by moving the same back and forth or up and down, it will be seen that the grooves may be readily cleaned or any deposits;

Having thus 'describe'd'my invention, what I desire to secure .by Letters or casing having a water inlet and an elongated wateroutlet, a flow obstructing member mounted for oscillationwithin said casing between the in.- let and outlet and provided with two rows of jet forming grooves.

3. A shower bath spray head comprising a shell or casing having a water inlet and an elongated rectangular water outlet, a flow obstructing. mem-v ber mounted for oscillation within said casing between the inlet and outlet thereof and having grooves in opposite sides which cooperate with the walls of said outlet in providing two spaced rows-of water jets.

4. A shower bath spray head comprising a shell or casing having a water inlet and'an elongated water outlet, a flow obstructing member mounted for oscillation within said casing between the inlet and outlet and having grooves in opposite sides which cooperate with the walls of said outlet in providing two spaced rows of water jets.

. 5. A shower'bath spray head comprising a shell or casing having a water. inlet formed for attachment with a water supply pipe, an elongated parallel sided water outlet, a flow obstructing member mounted for oscillation within said outlet and having its surface. located toward the interior of the casing flattened and its other surface formed as'part of a cylinder, a series of grooves on opposite sides of the flow obstructing member and extending from said flattened portion into said cylindrical portion and with the .walls of said outlet constituting jet openings,

baffle members located on the outlet side of said water outlet; one located on each side of said water outlet, and one, at the center thereof and means for oscillating said flow obstructing member.

6. A shower bath spray head comprising a shell or casing having a water inlet formed for attachment with a water supply pipe, an elongated parallel sided water outlet, a flow obstructing member mounted for oscillation within said outlet and having its surface located toward the interior of the casing flattened and its other surface formed as part of a cylinder, and a series of grooves on opposite sides of the flow obstructing member and extending from said flattened portion into said cylindrical portion and with the I Walls of said outlet constituting jet openings.

7. A shower bath spray head comprising a casing having a water inlet, a substantially rectangular water outlet, aflow obstructing member controlling said outlet and provided with two spaced rows of grooves which cooperate with the 'walls of said outlet to provide two rows of water jets; said flow obstructing member being formed in the nature of a cylinder with one side flattened; said grooves being formed in the cylindrical portion thereof; the flattened side of said member when said member is in operative position facing toward the interior of said casing; said member being capable of being oscillated so that said flattened side provides channels for flushing the device.

obstructing member mounted for oscillation within said casing between the water inlet and outlet,

a row of spray jets on each side of said member I I and formed by cooperation between said member and the walls of said outlet.

9. A shower bath spray head comprising a shell or casing having a water inlet and an elongated water outlet, shoulders projecting inwardly from opposite sides of said casing between the water inlet and outlet ends thereof, a flow obstructing member mounted for oscillation between the shoulders of said casing and cooperating therewith when in one position to provide two spaced spray openings.
